Acceleration of TNS HP COBOL Programs

The process of acceleration applies only to object files created in TNS mode by the

COBOL85 compiler (or by the cobol utility in the OSS environment of a TNS/R

system). Native-compiled programs cannot be accelerated. Accelerated object code

improves the execution speed of TNS programs on TNS/R and TNS/E systems. To

accelerate a TNS object file, use one or both of these tools:

•

The Accelerator on page 1-37

•

The Object Code Accelerator (OCA) on page 1-37

Figure 1-4 shows an SQL program file that has accelerated object code.

Caution. Because the Accelerator or OCA invalidates SQL program files, run the Accelerator

or OCA before you explicitly SQL compile the program to avoid having to recompile.
